Hereinafter, before looking at various embodiments implemented through the mobile terminal 100 described above, at least some of the components listed above will be described in more detail with reference to FIG. 1A.

The user input unit 123 is for receiving information from a user, and when information is input through the user input unit 123, the controller 180 can control the operation of the mobile terminal 100 to correspond to the input information. . Such, the user input unit 123 is a mechanical (mechanical) input means (or a mechanical key, for example, a button located on the front, rear or side of the mobile terminal 100, a dome switch (dome switch), a jog wheel, Jog switch, etc.) and a touch-type input means. As an example, the touch input means is composed of a virtual key, a soft key, or a visual key displayed on a touch screen through software processing, or a portion other than the touch screen It may be made of a touch key (touch key) arranged in the. On the other hand, the virtual key or the visual key can be displayed on the touch screen while having various forms, for example, graphic, text, icon, video, or these It can be made of a combination of.

Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, information on a surrounding environment surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control the driving or operation of the mobile terminal 100 or perform data processing, functions, or operations related to an application program installed in the mobile terminal 100 based on such a sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the action of allowing an object to be located on the touch screen without being in contact with the object to be recognized as being positioned on the touch screen is named "proximity touch", and the touch The act of actually touching an object on the screen is called "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies a touch (or touch input) to the touch screen (or display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. To detect.

As an example, the touch sensor may be configured to convert a pressure applied to a specific portion of the touch screen or a change in capacitance generated at a specific portion into an electrical input signal. The touch sensor may be configured to detect a location, an area, a pressure when a touch, a capacitance when a touch is touched, and the like at which a touch object applied to the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to an operating state of the mobile terminal 100 or an application program being executed.

Meanwhile, the touch sensor and the proximity sensor described above are independently or in combination, and a short (or tap) touch, a long touch, a multi touch, and a drag touch on the touch screen. ), flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. You can sense the touch.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than that of the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121, as viewed as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor are combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. The photosensor may be stacked on the display device, and the photosensor is configured to scan the motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing object according to the amount of light change, and through this, position information of the sensing object may be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100, or UI (User Interface) and GUI (Graphic User Interface) information according to such execution screen information. .

The haptic module 153 generates various tactile effects that a user can feel. A typical example of the tactile effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated by the haptic module 153 may be controlled by a user's selection or setting by a controller. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output them.

In addition to vibration, the haptic module 153 is designed to respond to stimuli such as a pin arrangement that moves vertically with respect to the contact skin surface, a blowing force or suction force of air through a jet or inlet, grazing against the skin surface, contact of an electrode, and electrostatic force. It can generate various tactile effects, such as an effect by the effect and an effect by reproducing the feeling of cooling and warming using an endothermic or heat generating element.

The haptic module 153 may not only deliver a tactile effect through direct contact, but may also be implemented so that a user can feel the tactile effect through muscle sensations such as a finger or an arm. Two or more haptic modules 153 may be provided depending on the configuration aspect of the mobile terminal 100.

The light output unit 154 outputs a signal for notifying the occurrence of an event using light from a light source of the mobile terminal 100. Examples of events occurring in the mobile terminal 100 may include message reception, call signal reception, missed call, alarm, schedule notification, e-mail reception, and information reception through an application.

The signal output from the light output unit 154 is implemented as the mobile terminal emits a single color or a plurality of colors of light to the front or rear. The signal output may be terminated when the mobile terminal detects the user's event confirmation.

The memory 170 may store a program for the operation of the controller 180 and may temporarily store input/output data (eg, a phone book, a message, a still image, a video, etc.). The memory 170 may store data related to vibrations and sounds of various patterns output when a touch input on the touch screen is performed.

The memory 170 is a flash memory type, a hard disk type, a solid state disk type, an SDD type, a multimedia card micro type. ), card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read (EEPROM) -only memory), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The mobile terminal 100 may be operated in connection with a web storage that performs a storage function of the memory 170 over the Internet.

Meanwhile, as described above, the controller 180 controls an operation related to an application program and, in general, an overall operation of the mobile terminal 100. For example, when the state of the mobile terminal satisfies a set condition, the controller 180 may execute or release a lock state limiting input of a user's control command to applications.

In addition, the controller 180 performs control and processing related to voice calls, data communication, and video calls, or performs pattern recognition processing capable of recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively. I can. Furthermore, in order to implement various embodiments described below on the mobile terminal 100 according to the present invention, the controller 180 may control one or more of the above-described components in combination.

Meanwhile, hereinafter, various embodiments may be implemented in a recording medium that can be read by a computer or a similar device using, for example, software, hardware, or a combination thereof.

Meanwhile, in the present invention, information processed by a mobile terminal can be displayed using a flexible display. Hereinafter, based on the accompanying drawings, this will be described in more detail.

2 is a conceptual diagram illustrating another example of a deformable mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the display unit 251. Such a deformable display unit 251 may be referred to as a'flexible display unit'. Here, the flexible display unit 251 may include all of a general flexible display, e-paper, and combinations thereof. In general, the mobile terminal 200 may include features of the mobile terminal 100 of FIGS. 1A to 1C or similar features.

A general flexible display refers to a light and sturdy display that is not easily broken because it is manufactured on a thin and flexible substrate that can be bent, bent, folded, twisted or rolled like paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which characteristics of general inks are applied, and the point of using reflected light may be different from conventional flat panel displays. Electronic paper can change information by using a twist ball or electrophoresis using a capsule.

In a state in which the flexible display unit 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display unit 251 becomes a flat surface. In a state deformed by an external force in the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, the information displayed in the second state may be visual information output on a curved surface. Such visual information is implemented by independently controlling light emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

In the first state, the flexible display unit 251 may be placed in a curved state (eg, a vertically or horizontally curved state) rather than a flat state. In this case, when an external force is applied to the flexible display unit 251, the flexible display unit 251 may be deformed into a flat state (or a less curved state) or a more curved state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the controller 180 (refer to FIG. 1A) may perform a control corresponding to such a touch input. The flexible touch screen may be configured to sense a touch input not only in the first state but also in the second state.

Meanwhile, the mobile terminal 200 according to the present modified example may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. Such deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means is provided on the flexible display unit 251 or the case 201, and may detect information related to deformation of the flexible display unit 251. Here, the information related to the deformation may be a direction in which the flexible display unit 251 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 251 is restored, and the like, In addition, it may be various pieces of information that can be detected due to the bending of the flexible display unit 251.

In addition, the controller 180 may change information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on information related to the deformation of the flexible display unit 251 detected by the deformation detecting means. It is possible to generate a control signal to control the function of.

Meanwhile, the mobile terminal 200 according to the present modified example may include a case 201 accommodating the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, a battery (not shown) provided in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top may be applied.

The state transformation of the flexible display unit 251 is not limited to being caused by an external force. For example, when the flexible display unit 251 has a first state, it may be transformed into a second state by a command of a user or an application.

On the other hand, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly holds and uses in the hand. Such wearable devices include smart watches, smart glasses, and head mounted displays (HMD). Hereinafter, examples of mobile terminals extended to wearable devices will be described.

The wearable device may be configured to exchange (or interlock) data with another mobile terminal 100. The short-range communication module 114 may detect (or recognize) a wearable device capable of communicating around the mobile terminal 100. Furthermore, when the sensed wearable device is a device that is authenticated to communicate with the mobile terminal 100, the controller 180 transmits at least part of the data processed by the mobile terminal 100 to the wearable device through the short-range communication module 114. Can be transferred to. Accordingly, the user can use data processed by the mobile terminal 100 through the wearable device. For example, it is possible to perform a phone call through a wearable device when a call is received from the mobile terminal 100, or to check the received message through the wearable device when a message is received by the mobile terminal 100. .

The watch-type mobile terminal 300 is configured to enable wireless communication, and an antenna for the wireless communication may be installed in the main body 301. On the other hand, the antenna can extend its performance by using a case. For example, a case including a conductive material may be configured to be electrically connected to an antenna to expand a ground region or a radiation region.

4 is a conceptual diagram illustrating a mobile terminal according to an embodiment of the present invention. Specifically, FIG. 4 shows a conceptual diagram of a divided area for providing information for guiding to a location for user authentication in relation to the front display of the mobile terminal.

Referring to FIG. 4, the display of the mobile terminal 400 may be divided into a plurality of areas. Specifically, based on the position of the display (hereinafter referred to as the reference position) 410 corresponding to the position of the sensor, a plurality of circles 420, 430, and 440 are arranged to have a specific interval 450, so that the area of the display is Can be distinguished.

The centers of the plurality of circles 420, 430, 440 may correspond to the reference position 410 (or the center of the reference position 410 ). The specific interval 450 is a predetermined distance interval, and may be, for example, a distance interval corresponding to the width of a user's finger (eg, thumb), but is not limited thereto.

The mobile terminal 400 may provide information for guiding the reference position 410 based on the plurality of circles 420, 430, 440. Specifically, when the mobile terminal 400 obtains an input related to user authentication, the mobile terminal 400 checks the difference between the acquired input and the reference position 410 and provides information for guiding the reference position 410 based on the confirmed difference. I can.

In an embodiment, when the mobile terminal 400 acquires an input related to user authentication, the mobile terminal 400 may check the difference between the input acquired on the display and the reference position 410. The mobile terminal 400 assumes a plurality of circles 420, 430, 440 centering on the reference position 410 and having a specific interval 450, and based on the number of circles between the reference position 410 and the input. Information guiding the reference position 410 may be provided.

In an embodiment, when the mobile terminal 400 obtains an input related to user authentication, the mobile terminal 400 checks the distance between the obtained input and the reference position 410, and assigns a weight based on the checked distance to determine the reference position 410 Guiding information can be provided.

For example, when an input is acquired in a region between the first circle 420 and the second circle 430, the mobile terminal 400 may provide the first vibration or the first sound. When the input is acquired in the region between the second circle 430 and the third circle 440, the mobile terminal 400 may provide a second vibration or a second sound.

In this case, the first vibration is assigned a first weight and the second vibration is assigned a second weight, and may be a vibration having a different intensity (or intensity) or a different vibration frequency. The first sound is assigned a first weight and the second sound is assigned a second weight, and may be a sound having a different loudness or a different sound. The first weight may be a value smaller than the second weight, but is not limited thereto.

According to an embodiment, the mobile terminal 400 may provide vibration or sound in proportion to a distance or distance range between the reference position 410 and the position at which the input is obtained as guide information. In this case, the closer the input is to the reference position 410, the smaller the intensity of vibration or the smaller the sound may be provided as information. For a more detailed example of the intensity of vibration or sound proportional to the distance or distance range, reference may be made to FIG. 5 or FIG. 6.

5 and 6 are diagrams for explaining an alarm or vibration provided by a mobile terminal according to an embodiment of the present invention. Specifically, FIGS. 5 and 6 show the intensity (or intensity, loudness) of vibration or sound with respect to the input separation distance.

In this case, the input separation distance may include a separation distance between a reference position on the display corresponding to the position of the sensor and a position at which an input applied from the user is obtained. Vibration or sound may be provided by the mobile terminal.

Referring to FIG. 5, the input separation distance and the intensity of vibration or sound may be proportional. Specifically, as the input separation distance increases, the intensity of vibration or sound may increase. In this case, as the position at which the input is acquired is closer to the reference position, the intensity of vibration or sound may decrease. Accordingly, the mobile terminal induces the user to move the input to the point where the intensity is reduced, so that the input is applied on the display corresponding to the position of the sensor.

Referring to FIG. 6, the intensity of vibration or sound may be provided in a discrete form. Specifically, the intensity of vibration or sound increases as the range of the input separation distance increases from the reference position, but may be set to a value that is distinct (or discontinuous) from each other. In this case, the range of the input separation distance may be determined.

In an embodiment, the range of the input separation distance may include a distance predetermined in relation to the finger width. For example, based on data that the average length of the thumb width of an adult is 1.2cm, the range of the input separation distance may correspond to 1.2cm. In this case, σ in FIG. 6 may correspond to 1.2 cm.

In this case, for example, when an input is applied to a portion corresponding to a radius of 1.2 cm from the reference position, vibration or sound of the first intensity may be provided. When an input is applied to a portion corresponding to a radius of more than 1.2 cm and less than 2.4 cm from the reference position, vibration or sound of a second intensity may be provided.

For another example, the sound of the provided sound or the form of the spoken sound may be different according to the input separation distance range. For example, when an input is applied to a portion corresponding to a radius of 1.2 cm from the reference position, the mobile terminal may provide a sound “Please move down a word of your finger”. When an input is applied to a part that is more than 1.2cm and less than 2.4cm in radius from the reference position, it can provide a sound saying'Please move under two fingers'.

Meanwhile, FIGS. 5 and 6 are only examples of the form of information provided, and the present specification is not limited thereto.

The processor 720 may check whether the location at which the input related to user authentication is obtained corresponds to a predetermined position (eg, the reference position 410 of FIG. 4) related to user authentication. Based on this, the processor 720 may check whether an input related to user authentication is applied to a predetermined position on the display 710.

In this case, the predetermined position may include a specific position on the display corresponding to the position of a sensor for recognizing biometric information. For example, the predetermined position may include a specific position, but may include an area having a specific radius around the specific position.

The processor 720 may provide information for guiding a predetermined location in relation to the identified location based on confirmation as to whether the identified location corresponds to the predetermined location. For example, when the identified location is not included in the predetermined location, the processor 720 may provide information for guiding the user's input to be applied to the predetermined location. In this case, the type of information provided may be predetermined, and may include, for example, at least some of vibration, sound, or content.

In an embodiment, when the identified position is different from the predetermined position or the confirmed position is not included in the predetermined position, the processor 720 is based on a circle having a different diameter and is centered on the predetermined position. Among the areas, you can check the area including the identified location. The processor 720 may provide information for guiding the predetermined location in connection with the user authentication by setting based on the identified area.

For example, when the identified location is different from the predetermined location, the processor 720 may check an area to which the identified location belongs among the divided areas of the display 710. The processor 720 may provide information for guiding a predetermined location based on a setting corresponding to the identified area.

The setting corresponding to the identified area may include, for example, vibration of a specific intensity, sound of a specific loudness, or predetermined content. Each of the specific strength and specific size may be determined based on, for example, a distance or range of distances between an identified location and a predetermined location. The distance range may be divided into a plurality based on an interval of a preset range from a predetermined position. In this case, as the value of the distance range increases, the specific strength or the specific size may increase, but is not limited thereto, and may be, for example, decreased.

The setting corresponding to the identified region may include, for example, information on a weight designated for each region. In this case, when an input is confirmed within the first area, a first weight is assigned to provide first information, and when an input is confirmed within the second area, a second weight is assigned to provide second information. . Accordingly, information based on the location where the input is confirmed may be provided.

In an embodiment, when the identified location is different from the predetermined location, the processor 720 may check information on at least one of a distance between the identified location and the predefined location, and a direction from the identified location toward the predefined location. Based on this, the processor 720 may provide information for guiding a predetermined location from the identified location.

The guided information may include information about a distance or information about a direction.

In an embodiment, when the location is confirmed, the mobile terminal may determine an area to which the identified location belongs among the areas of a predetermined circle so as to have a specific distance interval from the predetermined location. The mobile terminal may check the determined area to determine whether the identified location corresponds to a predetermined location in connection with user authentication. For example, the mobile terminal may determine that the identified location corresponds to a predetermined location in connection with user authentication when the identified location is included in an area within the first circle closest to the predetermined location. When the identified location is not included in the area within the first circle closest to the predetermined location, the mobile terminal may determine that the identified location does not correspond to the predetermined location in connection with user authentication.

The mobile terminal may provide information guiding to a predetermined location in connection with user authentication (840). The mobile terminal may provide information for guiding a predetermined location in relation to the identified location.

The mobile terminal can provide predetermined information in response to the identified difference. The predetermined information is the above-described guide information, and may include, for example, vibration of a specific intensity or sound of a specific loudness.

In this case, the specific strength or specific size may be designated based on a distance difference between the location of the identified input and the predetermined location. For example, a specific intensity or a specific size may be designated in proportion to the location of the identified input and the distance length of the predetermined location.

In an embodiment, the mobile terminal checks the area to which the identified location belongs among the areas of the predetermined circle to have a specific distance interval from the predetermined location, and provides information to guide according to the predetermined setting corresponding to the identified area.

For example, the mobile terminal may provide the first information when the identified location is included in an area between a first circle having a radius of 1.0 cm and a second circle having a radius of 2.0 cm around the predetermined location. . The mobile terminal may provide the second information when the identified location is included in an area between the second circle having a radius of 2.0 cm and the third circle having a radius of 3.0 cm around the predetermined location.

Here, the first information and the second information may be predetermined information. For example, the first information may include a vibration of a first intensity, the second information may include a vibration of a second intensity, and the first intensity may be less than the second intensity.

In some cases, the mobile terminal may check the coordinates of the identified location and compare it with the coordinates of the predetermined location to determine a direction from the identified location to the known location. In this case, the mobile terminal may provide information on a direction as guiding information. The information on the direction is information having directionality, for example, vibration indicating the direction. Content indicating a direction (eg, an arrow), text or sound including a term for a direction (eg,'Move to the right') may be included.

Meanwhile, the information on the direction may be provided as guiding information in an independent form, but is not limited thereto, and may be provided as guiding information together with the information on the distance. Here, the information on the distance may include information that does not have directionality, and may include, for example, vibration of a specific intensity or sound of a specific loudness.

In an embodiment, when the location of the identified input does not correspond to the predetermined location, the mobile terminal may check a direction from the location of the identified input toward the predetermined location. The mobile terminal can provide information on the identified direction. The identified direction can be expressed in various ways (eg, 7 o'clock, right). In addition, the information on the identified direction may be provided in various forms, for example, in the form of a sound or text saying'Move your finger to the 7 o'clock direction'.

According to an embodiment, the mobile terminal may identify a difference in distance between the location of the identified input and the predetermined location, and a direction from the location of the identified input toward the predetermined location, and provide guide information based thereon. For example, the mobile terminal may provide information to move in a specific direction by a specific distance.

Specifically, for example, the mobile terminal may provide information that guides a sound “Move two fingers in the direction of 7 o'clock”. For another example, the mobile terminal may provide information that guides vibrations that have a specific intensity and move in a specific direction.

In an embodiment, when a function related to user authentication is executed, the mobile terminal may check the type of user authentication. The type of user authentication may include, for example, at least one of a type related to payment, a type related to unlocking the lock screen of the mobile terminal, and a type related to identity authentication for a specific website.

For example, when an application that provides a user authentication function is executed, the mobile terminal identifies an application that was executed immediately before or an application that is executed in parallel, or identifies a signal that triggers user authentication, so that the type of user authentication is related to payment. You can check whether it is a type or related to unlocking.

More specifically, for example, when the user authentication function is executed while the shopping application is running, the mobile terminal may confirm that the type of user authentication is related to payment. For another example, when a user authentication function is executed based on an input being received while the home screen is locked, the mobile terminal may determine that the type of user authentication is related to unlocking. For another example, when a user authentication function is executed based on a signal being received from a payment server, the mobile terminal may confirm that the type of user authentication is related to payment.
